lconcretecars, and has for its object to prof' vide a new and improved car of this description.

Referring to the accompanying drawings, Figli-re l is a plan view of a car embodyingw theinvention; Fig. 2 is a side elevation; Fig. 3 is an enlarged cross sectional view; Fig. 4 is an enlarged plan view in part; seetion, and with parts omitted.

Like numerals refer to like parts throughthe several figures. f

[his invention is applicable to various kinds and classes of vehicles, and l have shown it illustrated in connection with a railway car. As herein shown the car may at the top'to the longitudinal piecef- 5. Di-

agonal braces-7 may be placed between the uprights 4. The parts are fastened together so as to form a metallic trame for the ear. The ywalls of the cai' are made up of coni'freto sections 8, and the doors ot' concrete sections 9. These concrete sections are preferably ot' concrete steel, that is. sections having; steel embedded therein. As herein shown the steel consists ol reinforcing'wires orrods il), 11 in the wall sections. and i12, 5, in the door sections. The wall and floor sections instead of havingr straight edges which ahnt are preferably provided with overlalipiin;A edges 14 and l5 (Fig. t). in the wall seetions the joint between the sect ions is ar ranged so as to come opposite the nprighls 4. The wall sections and floor sections prot'- eiably have an overlapping engagement .so

they inay move with relation to each other t to accommodate themselves to the conditions able arrangement may be used for this purpose. .\s herein shown the ends ol the tloor and wall sections are o'iooved so as to provide the overlapping; parts l? and 18. The wires or rods 1U in the wall sections are preferably coui'icctcd with the metallic iframe ot' the car. This may he done in any desired manner. .\s herein shown the upper ends or' these wires or rods pass through holes in the longitudinal pieces 5 and'aie heut so as to be held in place 'while the lower ends pass tl'iroutijh openings in the side beams l, and are bent or riveted in place. The wires l2 in the lloor sectii'ins pass through holes in the side beams, and arc bent or riveted in place. 'lhe corner at. the joint bctivccn thi` wall and 'floor Sections may bc lilled in as shown at ll). noted that by means ol' thisl i-.onstructiiui the .steel lramc ot thc car is completely protected by thc concreto sections so that the material in the car cannot come 'into contact with the steel trame to corrodc it, and that thert` is securcijl the strength ot' the steel ear. theI car at the saine tinal being non-corrosive.' This construction lprovides a car olf very p'rcat resistance and enduram-e. and one that can be easily and quickly rel'iaired in case ol accident. l'or thi" conciclc sections can he rcinoved `it inlii'ired. and easily and quickly replaced.

s rl`his construction in addition lo beingsr cheap to construct can also bc iuaiutainml at small cost. and is clcan and sanitary as \\'cll as water-prooi' and air-tigiht. l"or ihcse rcaYV sons it is particularly adapted l'or refrigerator cars. l'ruil cars. stock cars, and thc likc., `i'n elcclricnlty cduippcd cars thcrc is lilllc danger ol short circuits. ll'ilh this construction ihe cars are not all'ectcd hy varialions in temperature or moisture.

By mcuns ol' this invention lV provide what may bc called a con'iposilecar.
